Entity Microsatellite

DescriptionA repeating sequence within a genome which varies in the number of repeats between individuals. Short tandem repeats (STRs) or also called microsatellite.
Extremely rich source of genetic polymorphism is the microsatellite tandem repeat polymorphisms which display allelic variation
in the numbers of copies of short nucleotide repeat sequences. These short tandem repeats (STRs), consisting of di-, tri- and tetranucleotide repeats are currently the most informative and useful marker loci for gene mapping and other forms of genetic analysis .
Variability of short sequence repeats, for example, in ACTGTGTGCC (A is nt 1991), are designated as 1993(TG)3-6 with nucleotide 1993 containing the first TG-dinucleotide which is found repeated 3 to 6 times in the population.

Attribute Details

 Microsatellite Bp End Pos
DescriptionThe ending location for the tandem repeat.
bp = base pair(s)—one bp corresponds to approximately 3.4 Å of length along the DNA strand.
Base pair (bp): Two nitrogenous bases (adenine and thymine or guanine and cytosine) held together by weak bonds.
Two strands of DNA are held together in the shape of a double helix by the bonds between base pairs
For example, in ACTGTGTGCC, the first occurrence of A is 1991, but the last alphabet of the Tandem repeat [TG] in the nucleotide ends at 1998.

 Microsatellite Bp Start Pos
DescriptionThe starting location for the tandem repeat.

Base pair (bp): Two nitrogenous bases (adenine and thymine or guanine and cytosine) held together by weak bonds.
Two strands of DNA are held together in the shape of a double helix by the bonds between base pairs

For example:
In ACTGTGTGCC, the first occurrence of A is 1991, but the first alphabet of the Tandem repeat [TG] in the nucleotide starts at 1993
